2. Description of the Related Art Generally, building vibration absorbers are classified into two types, a spring type and a slide type, depending on the mechanical characteristics of the machine. At present, a friction one-side shaking support type vibration absorber is being developed in the industry. The friction one-sided vibration absorber has the characteristics and characteristics of the spring type and slide type vibration absorbers, and is reported in “V. Zagas. SS Low and SA Mahin, 19” by the Earthquake Research Center of UC Berkeley.

However, the principle of the friction one-side shaking support type vibration absorber is widely known.
At present, the following drawbacks are obvious in the industry. 1. The conventional friction one-side shaking support type vibration absorber has an incorrect structural design, and the configuration in which the constituent members come in contact with each other vertically is adopted.
The members are independent and not articulated. When an ascending action occurs during an earthquake (which is likely to occur in columns outside the building), the members of the vibration absorber are separated, the vibration absorbing function of the vibration absorber is lost, and the building is destroyed.

2. When the conventional friction one-side shaking support type vibration absorbing device is used for a long time, ash dust is accumulated, the sliding function is lost, and the vibration absorbing effect is lost. 3. The manufacturing process of the conventional friction one-side shaking support type vibration absorber is relatively complicated, requires a lot of time, and is not economical. Therefore,
An object of the present invention is to provide an economical vibration absorbing device that has a vibration absorbing function even when a rising action occurs, can be used for a long period of time, and is economical.

According to the vibration absorbing device of the present invention, it is provided with a base, a mounting base, a slide block, and a spring. An arcuate slide portion, which is recessed in the inner surface, is formed at the center of the top surface of the base. The slide block is installed inside the slide part, an arcuate surface with the same radius as the recessed surface of the slide part is formed on the bottom surface, and a hemispherical coupling part that is recessed is formed in the center of the top surface. ing. The mounting table is a flat plate, is installed on the top of the slide block, and has a connecting column formed at the center of the bottom surface, the end of which has the same diameter as the hemispherical surface of the connecting portion, and which is connected to the connecting portion. A predetermined number of springs are installed on the upper surface of the slide block outside the coupling portion. The spring has one end joined to the top surface of the slide block and the other end joined to the bottom surface of the mounting table. Therefore, the vibration absorbing device has a vibration absorbing effect against shaking and slipping, and the safety of the building is ensured. Further, since the vibration absorber is extremely sophisticated in structure, it is easy to manufacture and assemble, and the cost can be significantly reduced.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The vibration absorber according to the exemplary embodiment of the present invention includes a base 10, a mount 20, a slide block 30, and a spring 40. The base 10 has a circular, square, or polygonal shape, is clamped to the ground by bolts or anchor bolts, and has an arcuate slide portion 11 recessed in the inner surface at the center of the top surface. . A slide block 30 is installed inside the slide portion 11. The slide block 30 is smaller than the slide portion 11 and has an arcuate surface 31 formed on the bottom surface.
Since the radius of the arcuate surface 31 and the recessed surface of the slide portion 11 are the same, the bottom surface of the slide block 30 comes into close contact with the recessed surface of the slide portion and can slide smoothly. At the center of the top surface of the slide block 30, there is formed a recessed hemispherical coupling portion 32 that is joined to the mounting table 20. The mount 20 is a flat plate having the same shape as the base 10, and has the same area as or smaller than that of the base, and is fastened to the bottom end of the pillar of the building by bolts. The mounting table 20 is provided with a coupling column 21 at the center of the bottom surface. Since a hemispherical surface having the same diameter as that of the connecting portion 32 is formed at the end of the connecting column 21, the mounting table 20 is placed on the connecting portion 32 of the slide block 30. The slide block 30 outside the connecting portion 32 of the slide block 30
A predetermined number of springs 40 are installed on the upper surface of the same at the same distance in the same row. The bottom end of the spring 40 is hooked on the top surface of the slide block 30, and the top end is hooked on a hook stop 22 on the bottom surface of the mounting table 20. The mounting table 20 can swing on the upper part of the slide block 30, and a spring 40 acts between the mounting table 20 and the slide block 30 so that the mounting table 2 can be swung.
The force to restore 0 to equilibrium occurs. Since the force for the platform 20 to restore to balance acts on the slide block 30, the members do not separate when the action of rising occurs. Spring 4
When 0 is replaced by a damper device, the energy removal effect is improved. Further, since the slide portion 11 of the base 10 is formed in an arc shape, the slide block 30 accumulates potential energy when sliding. Therefore, the slide block 30 quickly returns to its original position after sliding.

As shown in FIG. 8, according to the vibration absorbing device of another embodiment of the present invention, the bottom end of the coupling column 21 has the same shape as the radius of the arcuate surface 31 of the base 10. As shown in FIGS. 9 and 10, according to another embodiment of the vibration absorbing device of the present invention, the base 10 or the mounting base 20 is combined with the rubber supporting plate 70 to improve the vibration absorbing and energy removing functions. There is. As shown in FIG. 11, according to a vibration absorbing device in accordance with another embodiment of the present invention, the coupling column 21 is disposed in the central portion of the top surface of the slide block 30, and the coupling part 3 is provided.
2 is arranged in the center of the bottom surface of the platform 20. Since the radius of the hemispherical surface at the end of the coupling column 21 is the same as that of the coupling part 32, they are closely joined and have the same function as that of the embodiment shown in FIG. Therefore, the vibration absorbing device has the original vibration absorbing effect, and the safety of the building is secured. Further, since the vibration absorber is extremely sophisticated in structure, it is easy to manufacture and assemble, and the cost can be significantly reduced.
